SHEET-METAL WARE.

SPECIFICATION forming part of Letters Patent No. 664,070, dated December 18, 1900.

Application filed April 29, 1897. Serial No. 634,366. We model.)

To all whom it may concern.-

Be it known that I, FRANK WILEY, of New York, (Whitestone,) in the county of Queens and State of New York, have invented a new and useful Improvement in Sheet-Metal Ware, of which the following is a specification.

My invention relates to an improvement in sheet-metal ware, in which the bodyis formed in any ordinary manner and the end formed by swaging a flat disk into cup shape of taper form, the upper portion of the taper cup having adiameter corresponding to the inner diameter of the body portion and the lower por tion of the said taper cup having a diameter corresponding to the inner diameter of the said upper portion, the upper portion of the said taper cup, when severed from the lower portion, forming a rim for the body and the lower portion of the taper cup forming an end closure.

My invention further contemplates providing the rim of the body portion or the rim of the end closure with one or more projections to form a narrow open crease between the rim of the end closure and the rim of the body portion to admit of inserting a tool or implement for loosening the end closure.

In the acoompanying drawings, Figure 1 represents a completed can or box inside ele' vation. Fig. 2 represents the same in longitudinal section. Fig. 3 represents the blank which forms the body portion. Figs. 4 and 5 represent the disks from which each of the rims and end closures are formed. Fig. 6 represents an end view of the body portion before the rims and end closures have been engaged therewith. Fig. 7 represents one of the disks after it has been swaged into cup shape of taper form. Fig. 8 represents the completed rim and end closure, and Fig. 9

represents a top plan view of the can or box.

The body portion A may be formed in any ordinary manner. In the presentinstance it is shown as a cylindrical body of sheet metal having its sides overlapping, as shown at Ct, which overlapping sides may be secured together by solder or in any other suitable manner.

B represents a flat disk of sheet metal from which the rim 1? and end closure b are formed in the following manner: The said fiat disk is swaged into cup shape of taper form by means of a suitable die, (not shown,) the upper portion of the taper cup being caused to have a diameter equal to the inner diameter of the body portion A. The taper of the cup thus formed is such that the lower portion of the cup will have a diameter corresponding to the inner diameter of the said upper portion. The upper portion is then severed from the lower portion along the line b (see Fig. 7,) the upper portion serving for a rim and the lower portion for the end closure. of the rim portion is preferably crimped over to form an exterior circumferential bead or flange b and the upper edge of the end closure I) is also preferably crimped to form an exterior circumferential bead or flange b the latter being provided with one or morein the present instance threeprojections b, which by contact with the rim of the body serve to space the rim of the end closure from the rim of the body. The projections may be made upon the rim of the body portion instead of upon the rim of the end closure, if so desired. The space so formed serves to admit the point or edge of a tool or implement to pry the end loose. The parts are assembled by bringing the ends of the body portion A into engagement, then inserting the rim b into the end of the body portion, and finally inserting the end closure 1) into the rim 1). One or both ends of the body may be closed in the above-described manner, as desired. The rim 1) when engaged with the body has a firm bearing around the inner wall of the body, and is thus prevented from liability to crack or split when the end closure is forced therein. The walls of the blank after being struck up in the first or drawing operation may, if so desired, be straight instead of taper, and after the end portion has been cut off either portion may at a separate operation be changed slightly in diameter to fit one closely Within the other.

What I claim is A sheet-metal can or box comprising a body portion, a jointless rim inserted in the end of the body portion and resting in contact with the interior of the body portion and an end The upper edge closure having its Wall constructed to fit the tions to prevent the said rim and closures interior of the said jointless rim, the said from restingin close contact, substantially as jointless rim and closure being provided with set forth.
